There is no DVR in the install. Plasma's are fed by RF so each IP camera needs to be converted to Analogue and then multiplexed onto the RF cable network which goes to each plasma. In turn the plasma will then be tuned to the frequency on which the cameras are transmitted on.There is no vga cable running from a central location to each plasma.
I may have found a unit which can assist me. The Vivotek VI-RX7101. If anyone has experience working with this and AXIS cameras please let me know.
